COLONIE — A surveillance video released Tuesday shows a 6-foot-1, 235-pound construction worker fly into what would become a fatal rage in Gold's Gym.

In the six-minute tape released by Town Attorney Michael Magguilli, Chad Brothers pulls down exercise equipment and other objects at 6:18 a.m. Oct. 31 while running through the Latham gym.

Brothers, 32, flew into a fit of rage and violence at the gym, causing employees to summon police, who used Tasers, handcuffs and a baton to subdue him. Police shocked the Troy man with four to five times with Tasers.

One of the stun guns shocked Brothers in the chest. At one point, he grabbed the Taser from an officer and appeared to shock himself, according to police.

An investigation showed Brothers died from a medical condition known as agitated delirium, not from police actions, Albany County District Attorney David Soares determined. Toxicology tests also showed steroids in his system, police said.
